Here’s one little setting you can enable to make your iPhone’s battery last longer!

iPhone battery life!

iPhones have become pretty advanced from when the first one was released. They take amazingly better pictures, run graphics-intensive games, and handle complex processes while also managing to last a whole day without a single charge.

However, sometimes, your battery may fall short for the amount of use you get out of your iPhone. Thankfully, there’s one little setting you can enable to save your battery life in the day as well as in the long run.

The trick is to turn on Auto-Brightness from the Settings app. I’ll show you how to do that exactly in a minute. But before that, let’s see how exactly Auto-Brightness can help your iPhone save precious juice.

iOS Battery Rundown feature
Apple introduced a battery rundown feature with iOS 12.

Two pieces of technology are involved in this–the iPhone’s screen, and the proximity sensor embedded near the front camera. The screen contains pixels that draw significant power from the battery. And the power it consumes is relative to the intensity of the pixels at the time.

So, while manually controlling the brightness, you sometimes leave it to an intensity that is just extra light for your eyes. And that affects the battery subsequently. For example, leaving the brightness at higher levels at night or in dark environments when low brightness would be sufficient takes an unnecessary toll on the battery.

What Auto-Brightness does is, it uses the proximity sensor (which takes up way less power than the screen) to determine the perfect amount of pixel illumination required. And hence, it saves battery life by making sure the screen does not gulp power by exceeding unnecessary levels of brightness.

That said, here’s how to enable Auto-Brightness on your iPhone.
